FEED-WATER REGULATOR.

SPECIFICATION forming part of Letters Patent No. 319,959, dated June 16, 1885.

Application filed March 25, 1885.

To (LZZ whom it may concern:

Be it known that I, JOHN A. GREELMAN, of Rochester, in the county of Monroe and State of New York, have invented a new and useful Improvement in Feed-Water Regulator for Steam-Boilers, which improvement is fully set forth in the following specification, and shown in the accompanying drawings.

This invention is intended as an improvement upon my earlier invention shown in Patent No. 306,062, issued October 7, 1884; and it consists, mainly, in supporting the float at the end of a yielding horizontal tube or hollow arm and attaching a valve-rod to the tube, by which means the inflow-valve for the water is opened and closed as the float moves up and down.

Referring to the drawings, Figure 1 is a vertical longitudinal section of the inclosure for the float and valve-globe, showing the arrangement of the parts therein, a part of the float and supporting-tube being broken away and vertically sectioned; Fig. 2, a transverse section of the tube at the line so drawn to a larger scale, viewed as indicated by arrow y, drawn to show more fully the manner of attaching the valve-rod to the tube; and Fig. 3, a vertical diametrical section of the float drawn to a larger scale to show the same as originally cast.

Referring to the parts, A is the inclosure for the float B; G, the hollow springing arm or tube guiding the float; D, the valve-globe, up through which the water-supply for the boiler flows; F andG, pipes leading to the boiler, respectively, above and below the water-line; b, the supply-valve; s, the seat therefor; I, the major removable head of the inclosure A, and K the minor removable head therefor, both heads being rigid. The pipe 0 is threaded at its outer end and fitted to an internally-threaded orifice, n, in the head K, projecting slightly beyond the outer surface thereof, and provided with a pinch-nut, a. At the inner end the pipe is secured to the lower part of the float and communicates with the interior thereof at the bottom, soas to drain the same or carry off any water that may accumulate therein, the water being discharged at 0 outside of the head K. As the water rises in the boiler and inclosure A from (No model.)

the inflow it carries the float up with it, as indicated in dotted lines, the hollow springing arm or pipe 0 readily bending to the upward pressure against the float.

The valve 1) is joined to the arm 0 by means of a rod, 6, astrap, d, of the rod encircling the arm between two collars, 0 0, which serve to hold the rib in line.

The valve-globe or inclosure D for the checkvalve opens into the lower part of the inclosure A, being in a vertical position, and the valve-rod 6 passes up through said globe D and connects with the arm G within the water-space or interior of the inclosure A,avoiding the use of a stuffing-box or other packing for the rod. The valve closes by moving upward against its seat, as indicated by dotted lines. WVhen the float and arm are carried upward by the water rising in the boiler, which is on a level with that in the inclosure, the valve is closed, checking the inflow until the falling of the water and float again open the valve.

The flaring cup f on the inner face of the head K, concentric with the arm and orifice a, assists to support said arm by preventing its bending thereat and distributing the bending of the tube along the same. Were it not for the cup most of the bending or springing of the arm would take place next the head K, on account of which the arm would in time become weakened thereat.

The float B, I make substantially seamless. It is cast hollow with two small openings, 9 and h, formed'diametrically opposite, one of which is utilized in making the connection with the arm 0, while the other is tightly plugged, as at i. This substantially-continuous shell is much superior to shells made of several pieces soldered or bronzed together at the joints, which seamed shells or floats are very apt to leak.

What I claim as my invention is- 1. In a feed-water regulator for steam boilers or tanks, the combination of the float B, the rigid head K, and the springing arm 0 for the float secured to the head K, substantially as shown and described.

2. In a feed-water regulator, the hollow float B and hollow springing arm 0 for the float, in combination with the rigid perforated head K, the hollow arm passing through said head 4'.
